2.8 USB2 Redriver Solutions

Today I'm going to introduce TUSB213 Redriver and EVM which can extend signal reach with better signal quality, enable robust system performance, and help pass USB 2.0 compliance. When a USB high speed signal travels through long trees or cable, signal integrity will degrade due to channel loss, which will cause big errors in the receiver, resulting in poor system performance. USB 2.0 Redriver can help solve this problem.
TI is the only vendor offering USB 2.0 Redriver in the market today. TUSB21x Redriver family provides a rich feature set that improves signal quality with a small footprint and very low power consumption. In this demo, we're showing using TUSB213 EVM. We can connect fine meter USB cable for Apple CarPlay or Android Auto. Enable better interoperability between infotainment system and the phone through USB 2.0 interface.
Here is the eye diagram before and after TUSB213 Redriver over a five meter USB cable. We can see the eye diagram degradation of the five meter cable, which will fail a compliance test. By adding TUSB213 at the end of the five meter cable, the eye opens up with a good margin to pass compliance. TI's USB Redriver solution includes a family of devices with bi-directional redriving capability.
Adding DC boost, 5 volt VCC, and the PC 1.2 downstream charging feature. It further enhances USB 2.0 signal quality while compensating channel loss. Eliminating components such as LDO or PC 1.2 charging controller. Lastly, it reduces system band cost, enabling efficient board design with improved system performance.
